Made from long-lasting, BPA-free polypropylene fabric, this ingenious Grow Bag takes the guesswork out of harvesting. Simply reach through the ingenious side pocket into the soil to check on your planters and harvest the spuds that are ready. The result? Higher yield with less risk of waste. The patented Grow Bag fabric air-prunes roots for stronger, healthier plants. It also aerates soil, prevents heat build-up and allows excess water to drain away. Nylon handles make the bag easy to move. Fold for storage, reuse year after year.
